The North Pole Magnet has two sides, each with its own effect. The North Pole side relaxes and the South Pole side tightens.
Whether you use the magnet on the jaw or on the temple (eye), you should face the north pole side towards the skin. This is the side with the small point or N on the magnet.
The strength of the magnet is 12,200 gauss. Some say it is 22,000 gauss. The number 12,200 gauss appears in the text on the magnet.
